The Hippocratic Oath (2016)

Original title: ヒポクラテスの誓い

Makoto Tsugano is a medical intern. Recommended by physician Kojin Tsukuba, whom she respects, Makoto Tsugano receives training at a forensics medicine classroom. There, she feels the classroom has a weird atmosphere. Professor Tojiro Kosaki leaves the classroom and Makoto is alone in the classroom. She answers a phone call and hears a girl's voice asking "is that the place where autopsies are conducted?" The girl wants an autopsy performed on the body of a woman who died in a car accident. Her father was involved in the car accident. Even though the police conclude that an autopsy is unnecessary, Tojiro Kosaki presses ahead with the autopsy. Makoto doesn't understand Tojiro's excessive ways, but the autopsy reveals a hidden truth.
